Easy Repair Instructions

Our repair process is much different and faster than any other manufacturer. The steps are simple. (No need to remove the thermostat)

  1. Prepare the coolant system by flushing it out with plain water.
  2. Pour in the Thermalweld.
  3. Run the engine at 3,000 RPM’s for approximately 10 minutes. Usually, it takes less than 10 minutes to repair the head gasket.
  4. After the repair, the head gasket will be sealed but not fully cured. To fully cure the seal, drive normally at least 4 times in the 1st 3 days. The more the better.
